Description

Technical Field

[0001] This utility model relates to a construction hoist cage structure, and in particular to a construction hoist cage structure for improving ventilation in the field of construction hoist technology. Background Technology

[0002] Construction hoists, also known as building construction elevators, outdoor elevators, or construction site hoisting cages, are primarily used in high-rise and super high-rise buildings in cities, as the height of such buildings makes it extremely difficult to complete operations using scaffolding or gantry cranes. They are commonly used personnel and cargo transport machines in construction, mainly for the interior and exterior decoration of high-rise buildings, bridges, chimneys, and other construction projects. Their unique box-like structure provides both comfort and safety for construction workers. Construction hoists are typically used in conjunction with tower cranes on construction sites.

[0003] Chinese patent CN219823382U discloses a simple installation cage device for aerated concrete blocks. The utility model uses sheet metal of the enterprise's standard color to wrap the cage around itself to prevent loose stones and fragments from falling and injuring people during air transport.

[0004] Existing sealed hoist cages use sheet metal, which has good windproof, dustproof and waterproof performance, and provides better safety and privacy, making them suitable for high-altitude operations. However, the ventilation inside the cage is poor, especially in high-temperature or enclosed environments, which can easily lead to poor air circulation inside, affecting the comfort of operators and work efficiency. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that traditional cage structures are mostly closed designs with poor ventilation. Especially in high-temperature or enclosed environments, this can easily lead to poor air circulation inside, affecting the comfort of operators and work efficiency.

[0006] To address the aforementioned problems, this utility model provides a construction hoist cage structure for improving ventilation. The structure includes a cage with an entrance / exit. Symmetrical movable windows are installed at the top of both ends of the cage. A ventilation opening is located at the top of the cage. A flow guide plate is rotatably connected to the top of the cage, directly below the ventilation opening, via a connecting shaft. Limiting rings are symmetrically fixed to the top of the flow guide plate. A locking block is symmetrically fixed to the top of the cage, located beside the ventilation opening. A second rotating shaft is rotatably connected to the locking block. Ropes are symmetrically wound onto the second rotating shaft, with the end of the rope furthest from the second rotating shaft fixedly connected to the limiting ring. A second servo motor is fixedly connected to the top of the cage, with its output end connected to the second rotating shaft. A bracket is fixedly connected to the top of the cage, located beside the ventilation opening. A first rotating shaft is rotatably connected to the inner wall of the bracket. An electric actuator is fitted onto the first rotating shaft near the ventilation opening sidewall. A connecting plate is fixedly connected to the movable end of the electric actuator. Fans are symmetrically fixed to both ends of the connecting plate. A support plate is fixedly connected to the side of the bracket, with a first servo motor fixedly connected to the support plate. The output end of the first servo motor is connected to the first rotating shaft.

[0007] In the aforementioned construction hoist cage, by installing a deflector plate, natural air can be introduced inside, and the direction of the airflow can be controlled. Combined with a fan, the airflow is increased, and the cooling inside the cage is accelerated, allowing for different ventilation modes to be selected in different weather conditions.

[0008] As a further improvement of this application, the bracket is symmetrically fixedly connected to two end plates, and a self-rebound roller is rotatably connected between the two plates, with a baffle cloth wound on the self-rebound roller.

[0009] As a further improvement of this application, the side end of the bracket located below the baffle is symmetrically fixedly connected to an inclined support plate that is connected to the top of the cage. The top of the support plate is provided with a sliding groove, and the end of the baffle away from the self-rebound roller is slidably connected to the sliding groove through a slider made of magnetic material.

[0010] As a further improvement of this application, a pull rope is fixedly connected to the end of the slider away from the bracket, and the pull rope passes through the slide groove and extends to the side of the entrance and exit. A limit ball is fixedly connected to the end of the pull rope near the entrance and exit, and a positioning rod is fixedly connected to the side of the cage below the limit ball.

[0011] As another improvement of this application, a filter screen is connected to the top of the vent by screws, and the fan is positioned directly above the vent after rotating 90 degrees via the first shaft.

[0012] As a further improvement to this application, a controller for controlling the first servo motor, the second servo motor, the fan, and the electric actuator is fixedly connected inside the cage.

[0013] In summary, under normal weather conditions, the second servo motor can be activated by the controller to drive the second rotating shaft to extend the rope. This allows the gravity of the guide plate to rotate through the connecting shaft and open the ventilation opening. The angle between the guide plate and the top of the cage can be adjusted according to the length of the extended rope, controlling the size of the ventilation opening. At this time, natural air can be introduced into the cage through the guide plate, and the airflow will not blow directly onto people's heads, causing discomfort. In hot weather, the first servo motor can be activated by the controller to drive the first rotating shaft to rotate the fan on the electric actuator by 90 degrees. Then, the electric actuator can be activated to extend the fan, making it horizontal with the ventilation opening and directly above it. At this time, the fan can quickly introduce air into the cage, rapidly cooling the cage. At the same time, the movable windows on both sides of the cage can be opened to allow air circulation. When the fan is not in use, it can be placed back in the bracket in a vertical position with the cage. The ventilation opening is equipped with a filter screen, which can intercept foreign objects outside the cage 1 and prevent dust. Attached Figure Description

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figures 1-2 and Figures 4-6 The diagram illustrates a construction hoist cage structure for improved ventilation, comprising a cage 1 with an entrance / exit. Symmetrically mounted movable windows 2 are located at the top of both ends of the cage 1. A ventilation opening 9 is located at the top of the cage 1. A guide plate 16 is rotatably connected to the top of the cage 1, directly below the ventilation opening 9, via a connecting shaft 17. Limiting rings 20 are symmetrically fixed to the top of the guide plate 16. A locking block 19 is symmetrically fixed to the top of the cage 1, located to the side of the ventilation opening 9. A second rotating shaft 18 is rotatably connected to the locking block 19. Ropes 22 are symmetrically wound onto the second rotating shaft 18, with the end of the rope 22 away from the second rotating shaft 18 fixed to the limiting ring 20. A second servo motor 21 is fixedly connected to the top of the cage 1, and the output end of the second servo motor 21 is connected to the second rotating shaft 18. A bracket 3 is fixedly connected to the top of the cage 1 at the side of the ventilation opening 9. A first rotating shaft 15 is rotatably connected to the inner wall of the bracket 3. An electric push rod 11 is sleeved on the side wall of the first rotating shaft 15 near the ventilation opening 9. A connecting plate 12 is fixedly connected to the movable end of the electric push rod 11. Fans 13 are symmetrically fixedly connected to both ends of the connecting plate 12. A support plate is fixedly connected to the side of the bracket 3. A first servo motor 4 is fixedly connected to the support plate, and the output end of the first servo motor 4 is connected to the first rotating shaft 15.

[0025] A filter screen 10 is connected to the top of the vent 9 by screws. The fan 13 is located directly above the vent 9 after rotating 90 degrees through the first rotating shaft 15. A controller (FX3U-32MR) that controls the first servo motor 4 (MSMD022G1 U), the second servo motor 21 (MSMD022G1 U), the fan 13 (R3G400-AA11-01), and the electric actuator 11 (DYT1000-500) is fixedly connected inside the cage 1.

[0026] Working principle: Under normal weather conditions, the second servo motor 21 can be activated by the controller to drive the second rotating shaft 18 to rotate, lengthening the rope 22. This allows the gravity of the deflector plate 16 to rotate through the connecting shaft 17, opening the ventilation port 9. The angle between the deflector plate 16 and the top of the cage 1 can be adjusted according to the length of the rope 22 extension, controlling the size of the ventilation port 9 opening. At this time, natural wind can be introduced into the cage 1 through the deflector plate 16, and the wind introduced through the deflector plate 16 will not blow directly onto people's heads, causing physical discomfort. In hot weather, the control can be adjusted... The device starts the first servo motor 4 to drive the first rotating shaft 15 to rotate the fan 13 on the electric push rod 11 by 90 degrees. Then, the electric push rod 11 is turned on to extend the fan 13 so that it is horizontal with the vent 9 and located directly above the vent 9. At this time, the fan 13 can quickly introduce air into the cage 1 to cool the cage 1 quickly. At the same time, the movable windows 2 on both sides of the cage 1 are opened to allow air circulation. When the fan 13 is not in use, it can be placed back in the bracket 3 in a vertical position with the cage 1. The vent 9 is equipped with a filter screen 10, which can intercept foreign objects outside the cage 1 and prevent dust.

[0027] By setting up the air intake plate 16, natural wind can be introduced into the room and the direction of the wind can be controlled. Combined with the fan 13, the wind force is increased, the cooling of the cage 1 is accelerated, and different ventilation modes can be selected in different weather conditions.

[0028] Second implementation method:

[0029] Figures 1-3 The bracket 3 is shown to have symmetrically fixed plates 5 at both ends. A self-rebound roller is rotatably connected between the two plates 5. A baffle 6 is wound around the self-rebound roller. An inclined support plate 7 connected to the top of the cage 1 is symmetrically fixed to the side end of the bracket 3 located below the baffle 6. A groove 23 is opened at the top of the support plate 7. The end of the baffle 6 away from the self-rebound roller is slidably connected to the groove 23 through a magnetic slider 14. A pull rope 8 is fixedly connected to the end of the slider 14 away from the bracket 3. The pull rope 8 passes through the groove 23 and extends to the side of the entrance door. A limit ball is fixedly connected to the end of the pull rope 8 near the entrance door. A positioning rod is fixedly connected to the side end of the cage 1 below the limit ball.

[0030] Working principle: In hot weather, when it rains, the limit ball can be held from the outside of the cage 1 and the pull rope 8 can be pulled. This will cause the cover 6 to slide down and unfold in the slide groove 23 through the slider 14, covering the top of the cage 1 and blocking the ventilation opening 9. At this time, the pull rope 8 can be wrapped around the positioning rod and tied to position the cover 6, so as not to affect the ventilation opening 9 to ventilate the cage 1, nor to affect the use of the fan 13. When the weather is sunny, the pull rope 8 can be untied. At this time, the cover 6 will automatically rewind and reset through the self-rebound roller.

[0031] By setting up a baffle 6, the ventilation opening 9 can be blocked from opening during hot and rainy weather, allowing it to open as usual and the fan 13 to cool the inside of the cage 1.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
